Tutorial 6 Multiplying a number by 11 To multiply any 2-figure number by 11 we just put the total of the two figures between the 2 figures. 26 x 11 = 286 Notice that the outer figures in 286 are the 26 being multiplied. And the middle figure is just 2 and 6 added up. So 72 x 11 = 792 Exercise 1 Tutorial 6 Multiply by 11: 1) 43 = 2) 81 = 3) 15 = 4) 44 = 5) 11 = 77 x 11 = 847 This involves a carry figure because 7 + 7 = 14 we get 77 x 11 = 7147 = 847. Exercise 2 Tutorial 6 Multiply by 11: 1) 11 x 88 = 2) 11 x 84 = 3) 11 x 48 = 4) 11 x 73 = 5) 11 x 56 = 234 x 11 = 2574 We put the 2 and the 4 at the ends. We add the first pair 2 + 3 = 5. and we add the last pair: 3 + 4 = 7. Exercise 3 Tutorial 6 Multiply by 11: 1) 151 = 2) 527 = 3) 333 = 4) 714 = 5) 909 =
